Also, if that is the real service bulletin then wouldn't they automatically be replacing heads all the time? Where does it tell them how to replace lifters?

I had the lifters replaced first and that did not solve the problem so the head replacement was the second step.
The link below provides the TSB from another member with a good summary. It is for the lifter replacement. There is no TSB for head replacement. The other website made the process rather confusing and they just mixed data together. Ignore it.
Click the link below, it is the best link I found to date with a good summary and the lifter replacement TSB.
